This study addresses how verbal self-monitoring and the Error-Related Negativity (ERN) are affected by time pressure when a task is performed in a second language as opposed to performance in the native language. German-Dutch bilinguals were required to perform a phoneme-monitoring task in Dutch with and without a time pressure manipulation. We obtained an ERN following verbal errors that showed an atypical increase in amplitude under time pressure. This finding is taken to suggest that under time pressure participants had more interference from their native language, which in turn led to a greater response conflict and thus enhancement of the amplitude of the ERN. This result demonstrates once more that the ERN is sensitive to psycholinguistic manipulations and suggests that the functioning of the verbal self-monitoring system during speaking is comparable to other performance monitoring, such as action monitoring.
本研究探讨了在使用第二语言执行任务时，与使用母语执行任务相比，言语自我监控和错误相关负波（ERN）如何受到时间压力的影响。要求德荷双语者在有和没有时间压力操纵的情况下用荷兰语执行音素监控任务。我们在言语错误后获得了一个ERN，结果显示在时间压力下其幅度出现了非典型的增加。这一发现表明，在时间压力下，参与者受到母语的干扰更大，这反过来导致了更大的反应冲突，从而增强了ERN的幅度。这一结果再次证明ERN对心理语言学操纵敏感，并表明言语自我监控系统在说话过程中的功能与其他表现监控（如动作监控）相当。
